This invention relates to a method of and device for sinking and building a well, and more particularly to a method ofbuilding the casing made of brick, block, concrete the like; V i

An object of the invention is to readily build the well-casing while sinking a well, preventing any degrading of the soil during the operation.

1e Another object is to providelthe well casa ing having maximum strength and being completely water-proofed.

The method according to this invention consists in excavating the earth in a desired diameter and to a desired depth, building a foundation frame for supporting the wellcasing at the upper edge of the hole, leading out a plurality of arms from said foundation frame, mounting the suspension rods to the ends of said arms, securing stop member to each of said suspension rods near th-e lower end, mounting a supporting frame or frames 7 upon said stop members, laying material such as brick on the said supporting frame to form 2 the well-casing, filling up the space between the casing and the soil with material, then further excavating the earth, connecting another set of suspension rods to the first set of suspension rods, and repeating the similar operation of building the casing until the desired depth of well is reached.

The invention will now be described more in detail with reference to the accompanying drawings, which illustrate one mode of carry ing out the invention, and in which:

Fig. 1 is a vertical section through the device and the casing forming the uppermost part of the well.

In'carrying out the invention, the earth 1 is first excavated in a desireddiam-eter and in a desired depth. At the top edge of the hole thus made, an annular suspension foundation frame 3 consisting preferably of concrete or Fig. 2 is a partly sectional plan view therecylindrical'shape, and near the lower end ofeach suspension rod 5 a stop member 6 is secured. On said stop 'members6 are detachably mounted annular supporting frames 7 and '7. Then the first course of brick, blockor other suitable material is laid on said supporting frame 7, and by proceeding the laying operation upwardly, the outer wall8 V of brickwork is built. During said operation of making the outer wall f brick work,

"the space between the latter and the soil 1 is i filled up with waterproofing-material or with soil 9,.the'space being filled successively as the brick laying operation proceeds. The inner surface ofthe wall 8 is coated with a layer of water-proofing material 10. After said process, an inner wall 11 of brick work or the like is built in the similar manner as with the outer wall 8, leaving an annular space betweenit and the outer casing 8. Said annular space left between the outer and inner walls. 8 and 11 is filled" up with reinforced "concrete or other suitable material, forming thereby the intermediate wall 12, thus the upper part of the well-casing is completely built.

The earth is further excavated inside.

Then, another set of suspension rods 5"is connected to and suspended from the upper set of the suspension rods 5, as shown in chain lines in Fig. 1, and the operation of building the casing similar to the first step is repeated until a desired depth is reached. The well is thus built downwards.

The supporting frames? and 7 are removed when they have finished their service,

and the space left is filled up with brick, block or other suitable material. If desired, said supporting frames may be left embedded in the casing. In this case, the space is filled with cement mortar and the like.

' In thedrawings, 13, 13 designate the reinforcing bar in the foundation frame 3. 14 are bolts and nuts for securing the stop members 6 to the rods 5. 15 is a layer of water-proofing material on theinner surface of the casing. 2

indicates pile foundations.

From the foregoing, it will be seen, accord ing to this invention, that the casing of the 1 well can be readily built successively, and

that the maximum water-proofing quality and strength may be obtained.

What I claim is A method of sinking and building a wall, consisting in excavating the earth to a desired diameter and to a desired depth, building a suspension or foundation frame for supporting the well casing at the upper edge of the hole, leading out therefrom a plurality of arms, mounting suspension rods on the ends of said arms, securing a stop member to each of said suspension rods near the lower end,

mounting a supporting frame or frames upon said stop members, laying brick work on the said supporting frame to form an outer wall of a well casing in the position it is to occupy, building an inner wall spaced from the outer wall, filling the space between the inner and outer walls with concrete, filling up thespace between the outer wall of the casing and the soil with material, then further excavating the earth, connecting another set of suspension rods to the first set of suspension rods, and repeating the operation of building a section of the casing until the desired depth of well is reached.

In testimony whereof I affix my signature.
